Configurer le réseau WAN avec dd-wrt
Configurer le réseau WAN avec dd-wrt
Hey there. In short, I got a Netgear Nighthawk M1 to act as a modem for my TP-Link Archer C7. After flashing dd-wrt (v3.0-r38840), I got a WAN IP, but internet isn’t working. IP passthrough and DHCP are turned off on the M1 LAN settings. My network address is 192.1681.1 with a subnet mask of 255.255.255.0. On the Archer C7’s WAN connection, I’m using automatic configuration with DHCP set to local IP 192.168.2.1 and a gateway of 192.168.1.1. I’ve tried various IP settings for both devices, but nothing connects. I think I might be missing something important. Best regards.
Yes, your Netgear Nighthawk M1 has an IP address, and the TP-Link C7 ARCHER C7 uses a quick fix. I updated it back to the original firmware, and everything is functioning properly now. It seems the stock firmware automatically sets some parameters, which I’ll need to adjust manually in DD-WRT.
The problem stems from the M1 functioning as a modem/router, leading to potential double NAT issues. Most LTE carriers employ carrier-grade NAT, which could push you into triple NAT scenarios—making it tricky even if internet traffic reaches the Archer C7. I should check if switching the M1 to bridge mode simplifies things. Another concern is IPv6 usage; on TMobile you’re relying heavily on it, and from what I understand, DDWRT doesn’t auto-configure IPv6. You’ll need to manually configure it when using a Comcast router. You’ll also need to investigate your ISP’s IPv6 settings since they can set up the protocol in several ways.
It's in "bridge mode already, by enabling IP-passthrough, and disabling DHCP (as netgear recommends to do) We don't have TMobile in Denmark, and i'm am running IPV4. If i connect my M1 directly to my pc, i can see a different IPV4 every past 24 hours or so, same goes for default gateway and DHCP server. But primary/secondary DNS stays the same. You might be right on the NAT assumption. Subnet mask is 255.255.255.255 when directly connected, but my "mobile router setup) says 255.255.255.0. But. I've played around with the settings, and maybe i'm on my way to figure it out. (Setup -> Basic setup -> Networking) there's a bunch of settings regarding internal hardware routing. I've come so far to directly passing everything through the C7. But when it's done, i cant connect to my C7, and there's no internet at wifi. So its just a direct route from WAN port to switch, not passing through the router part. Does it make sense?
